Patented Mar. 18, 1930 UNITED STATES PATENT OFFICE oswALn w. KLIN'GSICK,OF ST. LOUIS, MISSOURI, AsSre-iuon 'IO DAY-BRITE REFLECTOR COMPANY, OFST. LOUIS, MISSOURI, A CORPORATION on MISSOURI LIGHTING FIXTURE nonsIIow oAsns Application filed April 21,

My invention relates to electric lighting fixtures for show cases andthe like and has for its principal object a fixture that is simple inconstruction, easy to assemble and disassemble and neat in appearance.The-invention consists partly in the means for holding the light socketmembers and reflector members in position in the trough or body member.The invention further consists in the lighting fixture and in the partsand combinations and arrangements of parts and in the processhereinafter described and claimed.

In the accompanying drawing, wherein like reference characters indicatelike parts Wherever they occur,

Fig. 1 is a bottom view of a lighting fixture embodying my invention;

Fig. 2 is a cross-sectional view of the socket members; and

Fig. 3 is a partial longitudinal view thereof on the line 33 in Fig. 2.

A trough or body member 1 adapted to be mounted in a show case or thelike is provided with inturned flanges 2 along its edges. Disposed insaid trough 1 are a plurality of double socket members 3 each adapted toreceive an electric light bulb 4 on each side thereof. In the drawingare illustrated bulbs of the kind commonly used in illuminating showcases, namely: bulbs that are'relatively long and of relatively smalldiameter. In one end of the trough 1 is a single socket mem: her 5adapted to receive an electric light bulb 4. Each socket member (3 and5) is held in the trough or body member 1 by means of a strip of springmetal 6 disposed in the recessed middle portion of said socket memberand having flanged ends 7 that fit in the inwardly bent flanges 2 of theedges of the trough. The socket members 3 and 5 are thus held againstlongitudinal movement.

A socket member may be removed by disengaging the retaining member 6from the flanges of the trough.

The socket members 3 and 5 have spring clips 8 secured thereto as byscrews 9 and extending along the portion that fits in the interior orrear portion of the trough 1.

member 5 is a reflector member 10 that has a cross-sectional shaperoughly approximating that of the trough member, but spaced away at therear portion from the rear of the trough so as to leave a channel 11 toreceive the electric wiring 12. The socket members have shoulders 13against which said reflector members-1O abut. Each reflector 10 isprovided with an-opening 14 adjacent to each. socket memberand eachspring clip8 has a tongue 15 at the end fitting in anopening 14 of areflector member 10, thus preventing accidental disengagement of thereflector member from the socket member but permitting separation ofthetwo when desired.

Eaehspring clip, 8 has rebent flange portions 16 that are bent aroundthe electric wiring .12that,suppliescurrent for the lights,

thus holding said wiring imposition.

The above described construction permits the assembling of a pluralityof socket members and reflector members with the necessary electricwiring extending along the backs of the reflector members and socketmembers and held in place by the rebent flanges of said clips and theinstallation thereof as a unit in the trough member. Preferably at leastone edge of the reflector members fits in a flanged edge of the troughmember. The joints between reflector members occur at the socketmembers, thus giving the fixture a very neat appearance. The fixture mayeasily be assembled and disassembled and various combinations andarrangements may be made by using different sizes of reflectors andgreater or smaller numbers of socket members. Obviously numerous changesmay be made without departing from the invention, and I 'do not wish tobe limited to the precise construction shown.

What I claim is: V

1. In a device of the kind set forth, a socket member for an electriclight bulb, a reflector fitting over the end portion of said socketmember, electric wiring for said socket member extending along the backof said reflector member and a clip on said socket member overlappingthe end of said reflector memher, said clip having rebent flange membersengaging said wiring to hold it in place.
